Piedmont Airlines Flight 20, a Boeing 737-200, ran off the end of runway 14 after landing at the Greensboro-High Point Airport, North Carolina. There were 92 passengers and 4 crewmembers aboard; 4 passengers and 1 flight attendant were injured slightly.
Flight 20 made an ILS approach to runway 14 and touched down at a faster-than-normal airspeed 2,600 feet beyond the approach end of the runway, during heavy rain showers. The aircraft ran off the end of the runway, and the three landing gears collapsed as the aircraft crossed a service road, 640 feet beyond the runway.
Probable Cause: "The probable cause of this accident was ineffective braking action caused by dynamic hydroplaning on a rain-flooded runway. Additional factors which contributed to the accident were: (1) An unstabilized downwind approach; (2) a relatively long, fast touchdown on a downsloping runway; (3) delayed deployment of the automatic spoilers; and, (4) failure of the crew to deploy the spoilers manually."
